“Anderson was concerned about Corey’s nondisclosure agreement with Trump,” said a source. “And whether CNN should point out he has one.”

Lewandowski’s legally prevented from criticizing Trump, and CNN technically should announce that to viewers ahead of each appearance. But a CNN rep insisted Cooper’s chilly reception of Lewandowski was “not true,” adding that on Tuesday night, “Corey was in fact booked on [Cooper’s show] ‘AC360’ . . . but the panel was bumped due to breaking news out of Turkey.”

Meanwhile, Politico reported Wednesday that Lewandowski lost a $1.2 million book deal with HarperCollins after failing to provide a copy of the now-mythic nondisclosure agreement.

The report claimed Lewandowski was shopping a book “tentatively titled ‘Let Trump Be Trump’ ” while working for the candidate. The project picked up steam again when Lewandowski was fired by Trump. But “HarperCollins asked to review a copy of the nondisclosure agreement,” Politico said.

“Lewandowski declined to do so, ultimately leading HarperCollins to decide not to renew its initial offer.”
